Variable-Frequency Drives

    July 27, 2006
    With a power range of up to 20 hp, applications for SMVector drives include packaging machinery, foodprocessing machinery, materialhandling/conveying systems, and HVAC systems.

    c These drives feature four modes of operation (V/Hz, enhanced V/Hz, vector speed, and torque), high starting torque, autotuning, advanced low-speed control, and dynamic speed regulation. Input voltage ranges from 120 Vac, single phase, to 600 Vac, three phase. The SMVector also includes drive memory in a removable chip, letting customers program multiple drives in seconds.
